First off, prerequisites for this are as follows:
 
Basic knowledge of Adobe Photoshop
Nova Launcher – however, this may also work with other Launchers I have not used.

 
 
1. Grab a photo of whatever picture you want as an icon.
2. Open up your photo with Adobe Photoshop – under the menu bar click on ‘Window’ and make sure ‘Show Layers’ is enabled.
3. Use the magic wand tool and highlight the part of the photo you want as an icon.
(Say you have a picture of you and your dog and you just want to use your dog as an icon)
4. After you have it highlighted the part of the photo you want, right click, and select ‘Layer via copy’
5. Then go up to ‘File’ and select ‘New’. You can name this whatever you’d like, for this write-up, we’ll call this new file ‘X’ Towards the bottom of that pop-up box you’ll see ‘Contents’ – you’ll want to select ‘Transparent’
6. Next, click back on your original photo. When you do this, you should see in the ‘Layers’ window, the part of the photo you highlighted. Grab this and drag it into the new file named ‘X’
7. Now on the ‘X’ file, go up to the menu bar and select ‘Image’ then ‘Canvas Size’ Adjust this accordingly to the size of your photo so the top and side edges are just about flush with your photo.
8. When this is done, go up to the menu bar and select ‘File’ and ‘Save As’ and select the Format as a .GIF file. Save the file to your desktop.

9. Plug your phone into your computer and mount your SD Card. Once that pops up, you can create a new folder on your SD card and call it ‘Icons’ or whatever your heart desires. Transfer file ‘X’ from your desktop into the “Icons’ folder on your phone’s SD card. Dismount your SD card.
10. Once back on your phone using whichever launcher you use, I used Nova Launcher go to your desired icon.
11. Long press and hold the icon, drag it up to the top right corner and let it go over "Edit"
12. You will see the stock icon and you will click that, it will bring up a menu to look for your icon file.
13. Select the Icons folder and pick the file we put in there called ‘X’
14. Your icon is now changed and press the checkmark at the top left of the window that was opened. It will ask you to crop your icon, if done correctly your icon will need no adjustments.

 
I will be posting a side by side tutorial on Android Icons in depth.
